Discount YG1 55593TE 1/2″ Size, 3″ LOC, 4 Flute, YG TiAlN Extreme Solid Carbide Finishing End Mill

Applications

The YG1 55593TE 1/2″ diameter, 3″ length of cut solid carbide finishing end mill is constructed to provide rigidity for precision machining in deeper slots and pockets with a 6.0x length-to-diameter ratio. Its four-flute design, paired with a 30° helix angle and YG TiAlN Extreme coating, balances chip evacuation and cutting edge strength, making it well-suited for free-machining steel and general milling. This combination ensures smooth finishes and consistent tool life across steels, cast irons, stainless steels, and HRSA materials. Since it lacks a corner radius, edge chipping resistance depends on the coating and flute geometry. The single end and center cutting features enable plunge cutting and versatile machining strategies. The YG TiAlN Extreme coating enhances heat resistance and wear properties, especially valuable under thermal loads encountered in steel machining. Avoid using this end mill on non-ferrous materials as the coating is poorly matched and will degrade rapidly. Its design and coating are not optimized for aluminum or copper alloys, which require different tool properties for effective chip control and surface finish.

Features

• Suitable for cutting hardened & high alloy steels, steel casting, chill casting, malleable cast iron, CrNi-steels, brass, copper, aluminum with a high percentage of silicon and abrasive plastics.
